A'T-r E ST UNITE STATES PATENT OFFICE. PETER LOUIE CANTELO-U, OF HILLSBORO, TEXAS sTEE RlNGrGEAR FOR TRACTION-ENGINES.

Patented Jan. 16, 1906.

Application filed June-26,1905. Serial No. 267,161.

To all whom it may concern: I

Be it known that I, PETER LOUIE CANTE- LOU, a citizen of the United States, and a resithe forward ends of a yoke 4. Bolted to the under side of the boiler ofthe traction-engine immediately behind the axle 1, is a transboiler being shown in dotted lines.

dent of Hillsbofo, Hill county, Texas,'have pelling vehicles driven by steam and adapted or use on roads andhighways.

My invention consists in a steam-cylinder rigidly-secured to the under side of the boiler to the rear of the front axle of the traction-en gine andsuitable connections from said cylinder to said axle.

My invention further consists in 'a suitable.

valve located convenient to theoperator and connections from said valve to the steamcyhnder, whereby steam is admitted to each end of the cylinder for shitting the gearing that is connected to the front axle to the engine. I

My invention further consists in certain;

novel features of construction and arrange 'ment of parts, that will be hereinafter more fully shown, described, and claimed.

In the drawings, Figure 1 is a plan view of the front wheels and axle of a traction-engine and showing my improved steering gear attached thereto, and the front end of the Fig. 2 is a longitudinal section taken on the line 2 '2 of Fig. 1. Fig. 3 is a transverse section taken on the line 3 3 of Fig. 1. section of the three-way valve 1 make use of in my improved steering-gear.

Referring bynumerals to the accompanying drawings, 1 indicates the front axle of a traction-engine or similar vehicle, on the ends of which are arranged the tractionver'sely-arranged cylinder'5, in which operates a piston 6, and the piston-rod 7 therefor Fig. 4 is an enlarged follows: When the traction-engine is moving transverse rods 10, that occupy positionsimoo mediately in front of and behind thecylinder5. These rods 10 are arranged to slide through bearings 11, that are bolted to the under side of the boiler. The forward one of these rods 10 is provided with a centrally-arranged integral arm 12, that is pivotally secured to the'rear end of'a pin 13, that is arranged to slide through a bearing 14, formed in the rear end of'yoke 4.

15 indicates a cylinder-valve casing, in

which is arranged to rotate a valve 16, the same being operated by a handle 17 Leading into the center to the front side of the valve-casing 15 is a" steamsupply pipe 18,

'that leads the steam from'the boiler to the valve. Leading from the cylinder 15 on each side of the pipe 18 are the steam-pipes 19 and 20, that lead to the ends of the cylinder 5. Leading outwardly from the cylinder 15, oppositefrom the inlet-pipe 18, is an exhaust-pipe 21.

The valve 16, that operates within the cylinder 15, is so connected that the inil'ei "118 andthe pipes 19 and 20 are open at the-sarrre time, so that steam entering through the p pe 18 passes in both directions through the pipes 19 and '20 into the cylinder 5 on opposite sides of the piston 6 therein.

When the valve 16 is rotated the proper distance in either direction, the ends of the wings of the said valve will pass by either one of the pipes 19 and 20, and as a result the opposite pipe will be in communication with the inlet-pipe 18, while the cut-off pipe is in communication withthe exhaust-pipe 21. T

The operation'of my steering-gears are as in va straight line, the handle 17 of the valve is heldin a central position in order that steam entering through the pipe 18 will pass will be held in the center of cylinder 5, and as a result the rods 10 will be held in a central position relative to the-body of a traction-engine, and the axle 1 will be correspondingly held, and thus the engines will move forwardly or rearwardlyin a straight line. When 1 1o the operator" of the engine desires to change the d ireoti on of travel, or, for instance, wishes to turn to the right, the valve-handle 17 is so manipulated that the inlet-pipe 18 and pipe 20 are in communication, and this movement opens communication between the pipe 19 and the exhaust-pipe 21. The steam now entering through the pi e 18 will pass through the pipe 20 'into t e right-hand end of the cylinder 5, and as a result the piston 6 will be moved to the left-hand end of said cylinder, while the pressure on the left-hand side of thepiston 6 will exhaust throu h the pipes 19 and 21. The piston-rod 7 Wi l necessarily be carried to the'left with the piston 6, likewise the rods 10 in their bearings 11, and as a result the pin 13 is shifted to the left, and in so doing it slides a short distance through the bearing i l-and at the same time turns upon the pin that hinges it to the arm 12. This action shifts the yoke 4 to the left in the position shown bydotted lines in Fig.

1, and as a result the axle is swung out of its transverse position and the wheels upon said axle are so shifted as that the engine is guided toward the right in its forward movement. The movements just described are necessarily reversed when it is necessary to shift the front axle and wheels to guide the engine toward the left.

The steering-gear of my movement coristruction is sim le,'strong,.and durable, isadapted for all e asses of traction-engines and road-rollers, and but very little mechanism is 5 required to accomplish the desired result.

.I clairn- 1. The combination with a traction-engine, of a cylinder arranged beneath the body of the engine, a'piston in said cylinder, piston-' rods projecting through each end of the cylinder, a frame connected to the ends of the piston-rods and arranged to slide therewith,

a yoke rigidly fixed to the front axle of the traction-engine, and a pivoted sliding connection between theframe and the yoke substantially as specified.

2. In a steering-gear for traction-engines, a cylinder arranged beneath the body of the traction-engine, a piston operating in said so cylinder, a iston-rod extending through each end of t e cylinder, a frame carried by, the ends of the'piston'rod, a yoke rigidly secured to the front axle of the engine, a bearing at the apex of the yoke, a pin pivoted to the center of the frame of the piston-rod and arrangedto slide in the bearing of the yoke, and means whereby fluid-pressure is admitted to each end of the cylinder substantially as specified.

. In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses. I
